What causes tires to cup on the inside tread?
Suspension components like shock absorbers, struts, bushings and others wear out with miles travelled. The result can be a tire that is no longer able to roll smoothly down the road; instead, it bounces slightly. This bouncing creates uneven points of pressure on tires, leading to tire cupping.
Is 9/32 A good tread depth?
New tires typically come with 10/32” or 11/32” tread depths, and some truck, SUV and winter tires may have deeper tread depths than other models. The U.S. Department of Transportation recommends replacing tires when they reach 2/32”, and many states legally require tires to be replaced at this depth.
What does 7 / 32 mean on a tire tread?
Another said the 7/32 means they’re still good but there’s wear. When a tire is brand new, is it 7/32? Or 32/32? My first pair of tires were bald (so I was told) by the time the car (a Honda Civic ’99) was only two years old. I did mostly highway driving back then.
What’s the tread depth of a worn out tire?
As mentioned above, tires are legally “worn out”. In most States when they reach 2/32″ of remaining tread depth. For example, a typical tire that starts with 10/32″ of original tread depth has only 8/32″ of useable tread depth. Its useable tread depth is calculated by subtracting a worn out tire’s 2/32″ from the new tire’s original depth of 10/32″.
How much tread does a new tire have?
Not sure what to make of it. A new tire tread will typically have 10/32 of an inch of tread, and some expensive tires may have 12/32 of an inch. So, 7/32 is pretty good, but is not comparable to a new tire.
What causes tire to wear evenly across tread?
If the vehicle was aligned correctly, this tire would have worn evenly across the tread, and stayed on the vehicle for another 30,000 or 40,000 miles. The second wear pattern that indicates a mechanical problem with the suspension of the vehicle is shown below on the left.
